If it's meds to bring the fever down get a supository, that's way too important NOT to get the right dose in her little body. If it's something else, try mixing it with a little soda, Dr. Pepper is good because it's so sweet and helps mask the taste. You may way to shake it flat so the bubbles don't discourage her.
I don't normally let my little ones drink soda, but a spoonful of sugar sure helps the medicine go down!! ; )
